I concur with a number of other respondents... To get the best glass you can afford. I found this article of top tier scopes tested extremely helpful in making my decision on my last scope. I'm very pleased that I took the time to thoroughly review it... and re-review it
Different things matter to each of us when we are looking to make a purchase like this, and this tested a wide array of scope features and qualities. Though the scope you selected initially isn't listed here, this might give you some other options to consider, or at least to think about in considering the exact scope you do want.
I am linking the results page, however, within it you can find links to optical clarity test, mechanical...etc. good luck and good optics to you!!!!
